My invention relates to shoe ornamenting machines and to devices for supporting and holding Work therein.

In my VPatent No. 1,681,038, of August 14, i928, I havedisclosed a particular type of shoe ornamentin g machine which has become known in the 'trade as a cut-out machine. This particular type of machine is provided with an anvil type Work support Which is normally movable from-a Work placing to a Work operating position, and clearance is provided so that fitted and closed uppers may be operated upon'.4 Prior to my invention the ornamenting ot shoes having open work designs in various positions on the up pers, was only possible With the pieces trom which the uppers of the shoes were to be made laid flat in a flat bed type ott machine so that the provision of a machine in which fitted and closed uppers could be operated on represented a distinct advance in the art.

The dies and Work supports for this type ot machineimay be of any desired form. VIt has, in seme instances, in the past, been customary to build up a combination o1e a base plate with the die supportrbuilt up from the base on rectangular metal blocks; This has been expensive and the assemblies have been cumbersome and unwieldy, and since this type of machine is usualiA operated by a girl worker, the lield et useliiilness of this type of Work support has been somewhat curtailed.

It is the object ot my invention to provide an assembly tor use in a shoe ornamenting 7 machine of either the cut-out or i Vflat bed type, which will be light and readily movable, Which will at the same time. be very sturdy, and in Which novel'supports allowing ample clearance for an assembled upper is provided.

lt is further my object to provide an sembly in which a plurality of die units may be combined on a single supporting base. so that, for example, one die unit will provide l the ornamenting device for the right side of a shoe, and another die unit Will provide the ornamenting` device vfor the left side ott the shoe. In my reference to die units l may include. the support for the die, the stripper 5G plate cooperating' with the die, and such other `guides and guards as Will ordinarily be required.

A further object is the provision of aplurality of spaced units so constructed and arranged that ample spacing is provided between the units to provide yclearance for the worlr,and Where desired to lenable an operator to employ the hands for holding the Work. Y

To the attainment of the foregoing "and other objects `which may hereinafter appear asthe description proceeds reference will be made to the 'accompanying figures of vdrawings, in Which:

Figure. 1 is a .plan VView of a double die unit assembly mounted on a. single support ing base. Y

Y Figure 2 is "a side 'elevation of the assembly shown in Figure 1 with the' presser membei" and the base of the machine also shown;

Figure 2a is a detail sectional view of the mounting plate and guide pin bushings.

Figure 3 is a plan view-of one` of the die units showing the position which a `closed upper will assume during the ornamentinfg operation, the die unit in this instance having its o'Wn individual mask for assisting in the accurate positioning and holding of the Work.

Figure 4 is a front elevation of a double die unit similar to that shown in Figure 1, with the units spaced so as to enable an operator to insert her hands between the units for holding the Work, as Well as providing clearance for the Work, the mounting of the stripper plates in this View being slightly modified. Y

The supporting base plate in the particular combination illustrated is indicated at 1 and in order to make the Whole assembly as light as possible, this base plate Will be 'constructed Vof a fibrous `resinol condensation product or other suitable composition. The base may have recessed guiding tracks, such as are indicated at 2, so that the vWhole assembly may be readily moved from a Work placing to a Work operating position Within the slides 2a of the machine frame.

At the rear end of the base I have indicated a support 3 which may be of fibrous composition, but which, in this instance, is composed of some light metal, such as aluminum. A mask is indicated at 4 and it will be noted that the mask is demountably attached to the support 3, the type of attachment, in this instance, comprising a pair of bosses .3a having tapered bearing surfaces 3?) which engage a iixed cone bearing 3c and a resiliently mounted cone bearing 3J which is adjustable for seating the bearing surfaces oi theI bosses by means of the pin 3e. The demountable attachment is similar to that described in my'V co-pending application Serial No. 327,072, `tiled. December 19, 1928. rPhe attachment is of particular convenience, asit is positioned with relation to the support so that it maybe quickly and readily demounted.

I have illustrated two die units, the one indicated at yA and the other at B. Each unit has a supporting or mounting plate 5 composed of light., tough composition similar to that of which the base 1 is composed. In order to mount the plates 5 securely on the base 1, I have provided a series of cylindrical tubular posts 6 composed of light, tough composition through which screws 7, countersunk in the base Las indicated at 8 are eX- tended. The ends of the screws are threaded indicated at 9, which provides a method for the attachment of the screws in threaded holes 10 in the plates 5.

In the use of substantially rectangular blocks, which has been customary in the past, for securing a die unit to a base plate the edges of the blocks have interfered with the ready positioning oi a closed upper in operating position on the die unit. The positioning o1" fitted uppers on the die units, when the die unit is supported on round pillars, is surprisingly easy as there are no sharp corners to catch and mar the work. Then, too, since one of my objects is the provision ol allight die unit assembly, great strength is achieved with.inconsequential weight.

f Each die unit has a stripper plate 11 on which I have shown a guide 12 or solid gauge 'which assists in the positioning of the work.

The stripper plate is resiliently supported on the base 5 so that when the presser head 13 is brought down into contact with the work the work will be carried back from engagement with the ornamenting dies v14A with the return ot the presser head.

As the thickness ot the plates 5, as shown in Figure' 2, is not sufficient to provide a positive guide for the pins on which the stripper plates arc'mounted, I have mounted in the plates 5 bushings 15 having upper portions of reduced diameter as indicated at 16. The pins on which the stripper plates are mounted are indicated at 17. The shanks of the pins fit within the apertures in the upper portions of the bushings 15 and the screws 18 provide heads for limiting the movement of the pins within the main apertured portions 19 of the bushings. Springs 20 surround the pin shanks as indicated, and these springs assist in pressing upwardly on the stripper plates after the ornamenting operation is completed.

In Figures l and 2 a single mask 4- is illustrated having cut-out portions 21l which are so positioned that one cut-out portion will serve to cooperate with one of the cutting dies and the other will cooperate with the other of the die units. In Figure 3 I have shown a die unit with an individual mask for each unit. In some instances such a combination is preferable.

Referring to the usc ot the combination shown in Figures l and 2, a closed upper, such as is shown in dotted lines at 22, is shown in position to have the right side of the saddle operated on by the unit A. The ornamentation for the opposite part of the saddle or facing may be accomplished by withdrawing the upper from the position shown and placing it in inverted position on the unit l. IVhile the plural die assemblies are shown with ornamenting dies for opposite portions of each shoe, it will be apparent that it may be advantageous to use both die units simultaneously. One die unit may also be for a right quarter and the other for a left quarter. Similarly diierent combinations of die units may be mounted regardless of the particular type of ornamentation to be done. The units may even be for di'lerent portions of the same upper, the combination thus providing mechanism increasing the amount of work that can be done over that which would be possible with a single unit.

In Figure 3 the ornamenting die shown is similar to that shown in Figures 1 and 2, the only difference being that the die unit has its own individual mask. I have shown the upper positioned on the cutting unit in a dilferent manner, the upper in this instance being in front and along the side of the unit, while in Figures l and 2, that part of the upper not to be operated on is in back and along the sides of the unit.

My invention, as exemplified in Fig. 1l, comprises a plural unit in which the ample clearance between the units A and B is clearly shown. This construction allows certain styles of uppers to be laid smoothly across the top portion of the die unit with other portions of the upper draped about its sides and with sutticient clearance, where desired, to enable an operator to manually hold the work on either unit. The stripper plates 11 in Figure 4 are resiliently supported in a dil"- ierent manner than is shown in Figures 1 and 2. The stripper plate in this instance is connected with pins 17a, having screws 18a, which provide heads for the pins. The pins pass through holes 19a. in the mounting plate 5. Springs 20a press upwardly on the stripper plate.

Another feature of great advantage is that if the upper surface of the dies is not in proper alignment, shims may be inserted under desired posts Without the necessity of removing the cutting plate or plates from the upper surface of the die support.

Various modifications in the mounting for the stripper plate, mask, solid gauges and die units will readily suggest themselves to those skilled in the art.

I consider the stripper plate support illustrated in Figure 2 in Which, for purposes of reducing the Weight, the bushings l5 are eniployed as one specific means for reducing the Weight of the unit, thereby being included as an important development in the provision of the light Weight die unit heretofore referred to. Y

Having thus described my invention, what I claim as new .and desire to secure by Let ters Patent is l l. In a shoe ornamenting machine the combination of a movable support, cutting dies mounted on said support having mountings spaced a substantial distance apart .and with clearance completely around said inountings, said dies being arranged With the cutting edges thereof normally lying'in a common plane, a stripping plate attached to each die,

each plate having portions for acting asV gauges in positioning Work to be cut by said dies, said plates being resiliently mounted relative to said dies, and a member toward Which the cutting edges of the dies are directed having a flat surface substantially parallel to the plane of the cutting edges of said dies.
